Filed Dec. 16, 1933 Patented a. 30, 1934 UNITED STATES PACKAGE LINERCharles G. Wood, Adrian, Mich., assignor to Simplex Paper Corporation,Adrian, Mich., a corporation of Michigan Application December 16, 1933,Serial No. 702,681

Claims.

This invention which relates generally to package liners is adaptedspecially for use in the packing of fruits vegetables, and the like, inbaskets or hampers. A disclosure of certain features of my invention iscontained in my application filed March 16, 1932, Serial No. 599,189.

The liner which is made of a suitable paper, such as chip-board, is ofelongated form bent around to present its two ends in meeting relation.The present invention is concerned particularly with a connectionbetween the meeting ends of the liner. According to the presentimprovements, I provide for a slip connection between the liner endsmade from interfitting tongues and slots, this connection being renderedpermanent, if desired. No parts other than elements integral with theliner are required for this purpose, although I prefer to use a stickerto join the locking tongues together. The opera- 20- tion of connectingthe liner ends may be performed expeditiously and simply without anymechanical aid whatsoever.

A suggestive embodiment of my invention is set forth in the accompanyingdrawing wherein- Figure 1 shows in perspective the present liner havingits two ends connected by tongues which a are joined by a sticker;

Fig. 2 is an enlarged vertical section through the connected ends of theliner taken on line 2-2 of Fig. 1; v

Fig. 3 is a view in elevation of the two ends, slightly separated;

Fig. 4 is a detail in section taken on line 4 of Fig. '1; and

Fig. 5 is a view in perspective of the liner applied within a bushelbasket for protecting a column of fruits, vegetables, or the like fromcontact with the basket walls.

A liner L of conventional form is illustrated in the drawing. Asshown,it 'is of elongated form with its opposite ends brought together forconnection. For convenience in packing and shipping, the liner iscreased or folded at diametrically opposite points so that it may lieflat. In order to conform to a container whose walls are tapered, forexample, a bushel basket B, the opposite longer edges of the liner-areof arcuate shape whereby the resulting liner will acquire the form ofatruncated cone.

In the construction shown, one liner end a, is provided with opposedtongues t extending toward each other and meeting centrally of theopposite edges of the liner. The tongues are defined by a single slit 3extending transversely 'of the liner through its centralportion spacedslightly from the liner end, a cut 0 extending inwardly from the linerend to the slit to separate the two tongues. By this construction Iprovide opposed tongues disposed transversely of the liner at one end,formed by slits extending 00 through the center region part way towardthe opposite edges.

Each opposite liner end b is equipped with a pair of openings 0 in theform of closed slots elongated in the direction of the liner length, and55 disposed about opposite the tongue ends which join with the liner.The length of the openings may be considerably more than the width ofthe tongues, perhaps twice as much, so that when the tongues areinterlocked with such openings the liner ends thus secured are stillfree to slide one upon the other in a longitudinal direction. Theconnection, thus made, is accomplished readily by bending and thenstraightening the tongues for inter-fitting within the openings. 15 Oncethis is done, the tongues will tend to remain in their locked positions.To make such connection permanent, if desired, a small strip of tape orpaper 1) may be adhered over the tongues t. This sticker or label whichmay carry 0 printed matter, as desired, is applied in place through awindow opening w between the slots 0, and remains visible therethroughas indicated clearly in Figs. 1 and 5..

In the packing of a container. as, for example, 35 a bushel basket, theliner may be called upon to contract or expand in longitudinaldirections, according to the manner in which the pack is made. Provisionfor all such movements is made by. the slip connection described. Thisconnection which is of exceeding simplicity may be made quickly at thetime the liner is used, or, if desired, at the factory before the lineris shipped.

When the liner ends are connected, prior to packing and shipping, thethickness at the joined ends will about balance the thickness at thecreased ends, so that a pile 0! such liners tied together or packed forshipment will make for greater economy in space.

I claim:

1. A package liner of elongated form having at one end slits whichdefine tongues extended transversely toward each other and at its otherend closed slots extended longitudinally with which the tongues areadapted to interflt to 105 connect the liner ends together, and meansjoining the adjacent ends of the tongues whereby to inseparabilize theconnection between the liner ends.

2. A package liner of elongated form having no at one end slits whichdefine ,tongues extendedtransversely toward each other and at its otherand closed slotsextended longitudinally with which the tongues areadapted to interflt to connect the liner endstogether, there being alsoa window opening between; the closed slots and means applicable throughthe window opening remaining visible therethrough joining the adjacentends of the tongues whereby to insep:

arabilize the connection between the liner ends. 3. .YA packageliner ofelongated form having opposite ends connected by transversely disposedtonguestormed integral with the liner at one end interfltted'with slotsformed in the other end of a length exceeding the width of the one linerend, and separate means insertable through the window. opening andremaining visible therethrough joining together the locking lip means ontheother liner end whereby to prevent disconnection of said cooperatinglockingmeans.
